Prairie Plants Close-Up: The Hidden World of Flowers and Fruit

Date: Monday, April 10th, 2017 Time: 7:00 pm - 8:30 pm Location: Mennonite Church of Normal (map and directions)


Everyone has many associations with a flower, the idea of flowers.  You put out your hand to touch the flower, lean forward to smell it?..or give it to someone to please them? ? Georgia O?Keeffe, 1939.  Flowers are indeed special to humans, yet why do plants make flowers in the first place?  Basically to reproduce.  Flowers are pollinated and become fruits.  Inside the fruits are seeds, which insure future generations.  Much of the diversity of flowers and fruits is the result of adaptations to attract some kind of animals to either visit the flowers to carry out pollination or to carry away seeds.  This presentation will use close-up photographs of a variety of flowers and fruits of prairie plants to show their innate beauty and structure and then explain how they are pollinated and dispersed.  This basic knowledge helps prairie enthusiasts understand some of the complexities of prairie ecosystems and how to select species for use in prairie plantings.
